The story of Oracle.DataAccess.dll version 4.112.3.0 is a classic tale of the "DLL Hell" that developers often face when working with the Oracle Data Provider for .NET (ODP.NET). This specific version is tied to Oracle Data Access Components (ODAC) 11.2 Release 3
If your application is "Any CPU" but you only have the 32-bit driver installed, it will fail on 64-bit Windows. You must match the application's process bitness to the driver. If you have multiple versions installed, use the setting in your web.config app.config to force the app to use the correct GAC Installation: This version is often registered in the Global Assembly Cache (GAC)
